Answer:
$8.27
Step-by-step explanation:
First we need to find the tip. We know it was 18% of the total. So...
x (the variable we need to find) 18%
__ = ___
10.08 (the total bill including tip) 100%
cross multiply
100x = 181.44
-------------------- (divide by 100 to get x by itself)
100
x = 1.81 (The 18% tip that was given)
So now we know how much the tip was, we subtract it from the bill
10.08 - 1.81 = $8.27
You use those points and first find the sloope. so change in y over change in x
then once you find the slope. you plug in the points into y=mx+b
ex: if you figured out that m=1 (the slope)
then y= 1x +b..so then say you know that one point is 1,1
so 1=1(1)+b so then b =1////
hope this helps
